Trump Signs Executive Order Unwinding Obama Climate Policies

Mr. Trump made clear that the United States had no intention of meeting the commitments that his predecessor had made to curb planet-warming carbon dioxide pollution, turning denials of climate change into national policy. At a ceremony, Mr. Trump directed the Environmental Protection Agency to start the complex and lengthy legal process of withdrawing and rewriting the Obama-era Clean Power Plan, which would have closed hundreds of coal-fired power plants, frozen construction of new plants and replaced them with vast new wind and solar farms.
